The main causes and methods of eliminating low beam headlights

Home » Repair tips » Headlights do not light - low beam does not work, diagnostics and repair 179

If your headlights are not on and your low beam lighting is not working, then driving at night with a faulty car is not only prohibited by traffic regulations, but also extremely dangerous. However, sometimes situations arise when the headlights go out during a trip. It is not always possible to spend the night in the car and finish the trip in the morning. We will tell you how to repair the exterior lighting of a car and how to get to the repair.

Low beam does not work: reasons

So, proper lighting of the road while the car is moving is a very important factor that ensures the safety of the driver, his passengers and other road users.
While driving a vehicle, the driver needs to clearly see the road along which the car is moving.

High/low beam headlights are very important because they provide good visibility both at night and in cloudy weather conditions. Today there are several types of car headlights, which can be divided into the following categories:

Main headlights using halogen, xenon, high-intensity discharge lamps, diodes, etc.;
Fog lights - the main purpose is additional illumination of the road while driving in thick fog (most often, the manufacturer already supplies cars with a set of fog lights);
Spotlight headlights - powerful headlights provide the driver with good visibility, especially when driving on unfamiliar roads (headlights are not intended for city driving, as they can blind other drivers);

At the same time, for low and high beams, as well as for fog lights, halogen lamps are most often used, designated by the type of base as R2, H1, H3, H4, H7, HB3, HB4.

As for the problem itself, if the low beam does not work, the reasons may be different. It is important that the cause of the malfunction of the low beam or high beam headlights is accurately determined. Here are some of the main reasons why the low beams do not light up:

low beam lamps have burned out;
the fuse threads have melted (since basically the power circuits of the left and right headlights are not interconnected and are protected by separate fuses, a failed one of the fuse elements can lead to the failure of one headlight), the malfunction is diagnosed visually. In case of difficult access to the mounting block, check the operation of devices receiving power from circuits protected by the same fuses;
faulty headlight relay (lighting systems stop working, there is either low or high beam). The malfunction can be detected by ear, by turning on the headlights and listening to the sounds that arise; if short, loud clicks are heard, the relay is working properly; if there are no clicks, the relay is faulty;
The connectors of the electrical wires going to the headlights are not connected correctly or are not connected at all (for example, they forgot to connect them after repairs). In this case, only one of the two headlights does not light up.
water entering the engine compartment of the car (oxidation of the “chips” at the junctions of the wires, as a result of which the “chips” cease to perform a conductive function). Diagnose the malfunction by checking all the named wires and connections suitable for the headlights;
voltage surge in the on-board network (both lamps burn out at the same time);
other non-standard reasons (for example, a crack in the headlight through which water gets in and moisture condenses).

Please note that if a malfunction is not identified, additional diagnostics of the electrical wiring are carried out using the procedure of “testing” the electrical circuits of the car with a multimeter. By the way, to quickly determine the cause, you need to make sure that there is power at the terminals

Of course, the lack of current at the terminals supplying the low beam headlight bulbs will result in no low beam.

By the way, to quickly determine the cause, you need to make sure that there is power at the terminals. Of course, the lack of current at the terminals supplying the low beam headlight bulbs will result in no low beam.

To diagnose such a malfunction, you must do the following:

insert a working lamp into the socket and “strike” the plus wire against the minus wire;
a spark jumping between the wires or the lamp turning on indicates the presence of current in the network and, accordingly, indicates a malfunction in the headlights or lamps themselves;
if there is no spark or the lamp does not light up, there is a break in the headlight power supply.

Please note that this method of checking is only suitable for simple cars where the ECM system is not complex. In turn, an attempt to short-circuit the plus and minus wires on many modern cars can lead to serious failures, errors in the ECU memory, etc.

Why don't the low beams come on?

In a Priora, the low beam may not light up for several reasons: the fuses have blown, the light bulbs have burned out, or the light switch (MUS) is faulty. Let's look at each of the reasons in more detail.

Headlight fuse

The possibility of failure of the low beam headlight fuse is possible, since with frequent use of the car, the load that the headlights take on heats up the fuse link and thereby disables it even without any current surges in the circuit.

It should be noted that the fuse protects each headlight individually, that is, failure of two fuses at once is unlikely. But it is recommended to start checking with them. These fuses are located in the prior mounting block under numbers F6 and F7 and have a fuse current of 7.5A.

If they are working properly, move on to the next point.

Burnt out low beam lamps

Burnout of lamps is possible due to long-term use and thermal overload. In the summer, when operating a car in the city with the headlights on, it does not provide proper cooling of the lamp, which often leads to burnout of the lamp filament. But, as in the case of fuses, failure of both lamps at once is unlikely.

All Lada Priora, regardless of the year of manufacture, are equipped with H7 type low beam lamps. But the high beam lamps will be different, namely with and without DRLs. Models with running lights are equipped with a high beam lamp of type H15, and those without running lights are equipped with type H1.

Light control module

Quite often, the MCC is the main culprit of this problem due to burnout of tracks on the board or oxidation of contacts. This can be treated by replacing the module with a new one or troubleshooting the old one with your own hands. You can understand that the reason is in the module by blinking the high beam; if the high beam is blinking and the low beam is not on, then in most cases the light control unit is faulty.

Lamp burned out

What to do if the reverse gear of a VAZ 2114 does not light up
{banner_content} Naturally, if any light source does not turn on, the first thing that comes to mind is that the light bulb has burned out. The design of car lamps is such that the low beam may indeed be absent, but the high beam remains available. Halogen lamps have two filaments. It is quite possible for one of them to rupture - in this case, the light for which it is responsible will be absent.

To replace the bulb, the services of an auto electrician are not required. It is enough to open the hood with the ignition off, remove the protective box on both sides of the headlight, pull out the contact group, disconnect the spring clips, remove the burnt out bulb and install a new one. A little subtlety:

The flask should be wiped with alcohol before installation, otherwise it will burn instantly. It is also not recommended to handle the bulb with unprotected hands: there is always some greasy and damp secretions on them, which can damage the light bulb. The best way to do this (replace the lighting) is with a dry cloth or rag.

Fuse blown

What to do if the airbag is on

An equally common reason why headlights do not light up. The block where all the car fuses are grouped is opened, the pinout of their location is taken and the required one is looked for. A burnt jumper is in most cases visible to the naked eye. Even a schoolboy can handle sticking a whole part into place, so a trip to the service station in this case will probably also be unnecessary.

By the way, if fuses blow with unenviable regularity, it means there is a breakdown somewhere in the wiring. Either wire the entire circuit yourself, or visit a professional electrician - problems with the wires can lead to all sorts of troubles, including a fire.

Wire problems:

And in very different places. You will have to check all the connectors at the connection to the relay and the fuse box. They may be poorly screwed and fall off; may oxidize and not pass current. In the first case, it is enough to tighten the clamping nuts; in the second, clean the contacts. You should also check the power button: very often the wire that leads to it becomes oxidized or comes loose. We can say that in domestic cars, first of all, you should inquire about the button, and only then go somewhere deeper.

Circuit breakers

Replacing a low beam lamp on a viburnum

This is the second most common cause of low beam failure. If the left headlight does not light, then it is worth inspecting fuse F6.

Where is he located? It is located in a block hidden under the steering wheel. To get there, you need to remove the protective cover, which is held in place by three clips.

When the right light fixture does not function, look at fuse F7.

The protective devices mentioned above have the same rating - 7.5 amperes. The easiest way is to replace the damaged fuse with a working one. If one is not at hand, then as a temporary measure a “bug” is installed, that is, a jumper made of any suitable piece of copper or aluminum wire. In a pinch, even regular foil will do.

It is worth knowing that frequent blown fuses clearly indicate problems with the wiring. As a rule, a malfunction here often occurs due to the fact that the insulation of current-carrying elements is frayed

It is important to find the defective location and insulate it as soon as possible, since the occurrence of a short circuit leads to a vehicle fire

What car enthusiasts say about the operation of low beam lamps

Importance of verification

“I had such a problem that the headlight began to shine dimly. I wanted to go buy a new light bulb first, but decided to test it first. I moved the right one to the left one, and it became clear that the reason was not the lamp at all. Then I dug around, searched, and found a melted fuse. After replacing it, the problem disappeared!”

If everything has been checked...

“If you are sure that you have checked both the bulb and the switch, but the headlight does not light, then the problem is definitely in the wiring.”

Where else to look for a problem?

“I had such a situation that the light bulb was one hundred percent working, and the relay switched, but the low beam still didn’t come on. Then I checked the contact connector in the engine compartment fuse block, it turned out there was a breakdown there. Maybe this information will help someone. Access to this block is from the side of the car wing.”

We recommend

“The headlight may not light if there are problems with the contacts. For example, the rubber seals often get wrapped up and the headlight does not fit tightly into the connector. On the left, between the air filter housing and the connector, you can lay a seal made of hard foam rubber, it really helps.”

If both low beam headlights go out

“I had a problem that the low beams on the “classic” were not on. As a result, it turned out that the tracks in the fuse box had burned out. In general, if you understand something about electrics, you will find the problem quickly and easily. In my case, we ran an additional wire under the steering wheel to the block.”

Replacement Tips

Speaking about replacing failed components of an electrical circuit, it is worth saying a few words about the correct replacement of light bulbs.

It must be done in the following order:

Turn off the ignition and remove the key from the lock.
Open the hood.
Unscrew the headlight unit (to do this, unscrew the bolts on both sides) and remove it.
Dismantle the contact group by disconnecting it from the reflector (this procedure should be done extremely carefully).
Once you find the spring clips, release them.
Remove the non-working light bulb.
Insert a new light bulb into the vacated socket.

Reassembly and installation of the headlight unit is carried out in the same sequence, but in reverse order. If necessary, a similar procedure can be performed with the second block. It is worth noting that it is highly advisable to replace lamps not with bare hands, but with light gloves - the glass of the bulbs is quite thin, and with strong pressure it can burst right in your hands.

Common causes of failure

In the photo: VAZ 2106 headlight high beam relay Most often, the low and high beam headlight relay on a VAZ 2106 car fails for the following reasons:

When the battery is working properly, there is no charging current, which is why it does not charge. This happens when the wires are poorly connected to the relay terminals or when the circuit from the generator to the battery is broken. Eliminated by fixing the wire in the circuit, checking and adjusting the voltage regulator and relay regulator.
Insufficient charging current with a discharged battery or high current with a fully charged battery is caused by a malfunction of the voltage regulator. It can be eliminated by adjusting the device or replacing it.
Burning and burnout of lamps with excessive heat occurs when the adjustment of the relay regulator is violated or the contacts are closed. Eliminated by disconnecting and cleaning the closed contacts, adjusting or replacing the voltage regulator.
High discharge current after stopping the motor. Occurs when the relay-regulator contacts close (contacts sintering, armature spring breaks) or the electrical wire short circuits. It is repaired by finding and eliminating a short circuit with the battery disconnected, checking and adjusting the current limiter, opening and cleaning the contacts, replacing the spring and adjusting its clearance and tension.

External signs of a breakdown of the VAZ 2106 light relay include the following aspects:

The low and high beam headlights stopped working.
Dimensions and turn signals stopped working

And there may be several reasons for its failure:

failure (burnout) of the contact plates inside the relay (popularly called “nickels”), reduction in their contact area, “sticking”;
breakage (burning) of the retracting and/or holding winding;
deformation or weakening of the return spring;
short circuit in the pull-in or holding winding.

If you find at least one of the listed signs, then the next step to fix the problem is to conduct a detailed diagnosis.

Why do low beam bulbs often burn out?

According to traffic regulations in force in the Russian Federation, low beam headlights must be on when operating a vehicle, regardless of the time of day. If the headlights on your car work properly, then there will be no problems following this simple rule. But what to do if low beam bulbs often burn out?

Let's look at the main reasons why headlight bulbs can burn out:

Lamps have a limited service life. This applies not only to the time of constant illumination, but also to a limited number of switchings. In addition, when you replace factory lamps with cheap analogues, you need to understand that their service life is shorter. Moisture gets inside the headlight. If the headlight is cracked, or the rubber seals no longer fit tightly between the glass and the headlight housing, there will inevitably be moisture inside. This is easy to diagnose yourself: a headlight whose integrity is compromised constantly fogs up. Errors during installation. If you do not follow the basic rules when installing halogen lamps, for example, not using gloves, then greasy marks remain on the headlights, which leads to a reduction in their service life. The power of the installed lamps is too high. It is better to choose lamps with reduced power, but with increased brightness, this way you can ensure excellent visibility on the roads in any lighting conditions. It is not recommended to install lamps with a power of 100 W. Manufacturing defect of the lamp. If a defective lamp is initially selected for installation - with a displaced spiral or a tilted bulb, it is not surprising that it does not last long and quickly burns out. Battery low. If the machine is used for many years, the old unit begins to quickly discharge. As a result of constant recharging of the unit, an overvoltage occurs in the on-board network of the machine. To diagnose this reason, you need the help of an auto electrician. Wiring problems

If the car was purchased from another car owner, it is important to check the wiring, as it can be damaged as a result of careless operation of the car. It must be remembered that if the wiring is faulty, it threatens to break not only the headlights, but also any electrical appliances of the car. Low resource lamp

Unscrupulous manufacturers put on the market lamps that initially have a short service life, and accordingly, they quickly fail.

Which bulbs are best for low beam headlights?

If you think that once you install a high-quality low beam lamp, you can forget about the need for replacement, then you are mistaken. From time to time you will have to change the optical elements anyway. But in order to remove and change the lamp as rarely as possible, you should choose the right element.

Today there are several types of light bulbs:

Incandescent - the simplest type, is a filament enclosed in a bulb. When the element operates, this filament is heated. With regular use, the thread will become thinner and eventually burn out.
Halogen - in this case, the filament is surrounded by a special halogen gas, due to which the temperature rises, which leads to improved lighting. The service life of halogen lamps is much longer than that of the bulbs described above, it reaches about 1000 hours.
Gas discharge - in this case, lighting is created as a result of heating gas under high voltage. Such devices usually use xenon, which is characterized by high luminous efficiency. To provide power and enable xenon, additional devices are needed, but in general such a system significantly increases the cost of optics. The service life in this case can reach 2 thousand hours.
LED light bulbs have recently become increasingly popular among domestic buyers. They can last up to 3 thousand hours or more depending on the manufacturer and usually have a white lighting color. It should be noted that LED elements provide better road illumination while consuming an order of magnitude less energy.

Why doesn't the low beam headlight light up? Troubleshooting

Almost every car owner has encountered a problem when the headlight does not light up “halfway”, that is, the low beam does not work. In this case, a situation arises in which the high beam lights up as if nothing had happened. At least a third of motorists have encountered this, and almost all of them had the idea that the problem was in the “headlights”, that is, the problem was in the optics, although in reality this is not always the case.

This malfunction is very familiar to VAZ car owners, who from time to time encounter this problem, even when they buy a completely new car. Often this problem affects the right headlight of the car, while the headlights on the left side of the car are not affected as often as the right.

But it would be a mistake to say that this only applies to Russian cars and their manufacturers; cars from foreign manufacturers are susceptible to the same problem. The difference is that each optical element, depending on the manufacturer, has its own shelf life and durability.

So, what should a driver do when there is a problem with the low beam? Every motorist has two options - contact a service station with a specialized specialist to solve the problem, or, saving money and sometimes time, fix the problem yourself

If you decide to fix the problem yourself, then you need to have the necessary tools for this and, most importantly, knowledge of the car's structure, including knowledge of the principles of the electrical circuit. If your low beam does not work, but there are no problems with the high beam, then the reasons for this may be several problems:

The light bulb doesn't work.
Broken, worn or shorted wires.
The fuse that supplies power to the low beam lamp has blown.
Other reasons.

You can fix this damage yourself. Moreover, knowing how to solve a breakdown related to headlights will be a help for every motorist, especially in a situation when the problem overtakes you on the road, and the nearest service station is several dozen, or even a hundred kilometers away. We will show you how to fix this problem yourself and present options for resolving it.

The lamp burned out

If your low beam does not work, then the first thing that comes to the car owner’s mind is that the filament has burned out. This is indeed possible, since the headlight design has two spirals, each of which has its own function. The peculiarity is that if one thread fails, the second one works normally. This applies to halogen lamps, which are more reliable and provide greater safety.

To replace the lamp, perform the following procedures:

Open and lift the trunk of the car.
Carefully remove the protective housing from both sides of the headlight.
Disconnect the headlight supply wires.
Disconnect the spring fasteners.
Disconnect the failed light bulb and install a new one.
Reinstall all removed parts in reverse order.

When installing the lamp, consider some features:

Before installing the lamp, use a clean cotton cloth soaked in alcohol to wipe the lamp. If you install a lamp that has greasy stains or dirty handprints, the lamp will burn out very quickly. Try to avoid contact of your hands with the lamp bulb, even if your hands are washed and clean. Wear cotton gloves or use a clean rag or tissue

This is very important for the life of your lamp.

Car headlights do not light: repair

If the driver is faced with the fact that the high or low beams do not light up, it is necessary to put into practice the available methods for repairing the headlights yourself. If the headlights burn out on the way, as a result of which it is not possible to continue driving at night, you can try to carry out repairs on the spot.

The fact is that many faults can be easily fixed independently, that is, there is no need to involve specialists, use special diagnostic equipment, repair equipment, etc. First, if the problem is burnt out lamps, and they are also available, they are simply replaced.

We also recommend reading the article on how to select and install DRLs on a car. From this article you will learn about what daytime running lights are, how they differ from fog lights, as well as how to install DRL (DRL) on a car and what needs to be taken into account as part of this procedure.

In other cases, the principle and sequence of repair work performed:

In place of the blown fuse, you can insert several cores from a stranded wire (one core can withstand 1 Ampere).
The veins are inserted either into the socket or wrapped around the fuse itself, while the contact surface should be pressed tightly against the homemade fuse element; You can replace a faulty relay with an analogue, which is used to turn on other high-voltage circuits (you can use an element for turning on the power window circuit or an element for turning on additional equipment, heated seats). Many vehicles have a dedicated backup socket with an unused relay.
To turn on the headlights, bypassing faulty elements of the power circuit, use wires of the required length and required cross-section (the ends of the wires are stripped of insulation and connected to a car socket for a portable lamp). You can also use a car cigarette lighter, connecting from the back of the power point, while the wires are connected directly to the terminals, the other ends of the wire are connected directly to the low beam lamp.

Taking into account the fact that almost all connectors of the elements discussed above are similar to each other. As a result, headlight damage can be repaired right on the road and you can get to your destination or service station for high-quality professional repairs.

Possible causes of failure

A car is a complex mechanism. Both used and new cars are not insured against failure of one or another part. When faced with an unexpected situation on the road, the main thing is not to panic, but to try to figure out what’s wrong and fix the problem.

List of common causes based on symptom diagnosis:

the lamp or fuse has blown;
the cartridge has failed;
short circuit;
problems in the charging system.

First of all, we check the fuse and lamps. If the problem is not with them, we move on, testing the light control module for performance. Sometimes, replacing a spare part does not give positive results. And all because the reason is the melting of the connecting chip. These actions help if the low and high beam headlights on the Kalina do not light up. Before buying a new LCM (light control module), you can carefully remove it and check whether the connections have oxidized. It happens that the wiring seems to be touching the board, but the current did not conduct, which was the cause of the breakdown. Then you should use a soldering iron to go over all the contacts. Put the board back and reassemble everything.

A common “disease” of the Lada “Kalina” associated with the cessation of light operation is halogen lamps. They burn out due to dust getting into the headlight, the lamp overheats and fails.
The second reason is increased voltage in the car’s on-board network. Using a tester, it is easy to find out what voltage the generator produces. When the engine is running, it should not exceed 14.4 volts. At higher rates, it may be necessary to replace the regulator relay.

Headlights flicker when the engine is running

Flickering headlights, although not too common, can also be a problem. They can be caused by:

Bad switch
Unusual resistance in the circuit
Weak or corroded connection
Poor circuit grounding
Bad multifunction switch

First, check whether both headlights are flickering or just one. If only one of the lights is blinking, concentrate on this part of the circuit:

Check the power and ground wires that connect to the headlight.
Check the electrical connector.
Inspect the lamp socket for corrosion or loose wire at the connector.

If both lights blink, check the part of the circuit that controls both lights:

Switch the switch to low and high beam and see if the lights flicker in both modes.
Check the switch.
Check if the wires on the switch are loose.
Check the multifunction switch.
Check the power side of the circuit for a loose wire or connector.

You may need a diagram for your vehicle model to trace the connections and connectors.

Wear and electrical problems can cause the light to dim.

Possible causes of malfunction

So, if the low beam in one of the headlights of a Lada Kalina does not light up, then the reason most likely lies in a burnt-out light bulb. Replacing it will not be difficult for every car owner.

However, unfortunately, there are a number of other reasons for this malfunction, the most common of which are the following:

The contacts in the plug block are oxidized or burnt;
The fuse has blown;
Open circuit;
The relay has failed.

Below we will look at how to fix all these problems.

Replacing the lamp

Replacing the low beam on Kalina is quite simple. Moreover, you will only have to spend a few minutes of your time on this.

The only thing is that before replacing old lamps, you need to purchase new ones of the H7 standard. It is advisable to install new bulbs on two headlights at once so that they provide the same glow.

Note! On sale you can find several types of H7 standard bulbs - halogen, xenon and LED, for example, for fog lights on a VAZ 2110. All their types have different prices, but the main thing is that they have different characteristics

On our portal you can familiarize yourself in detail with the features of all these lamps.

Replacement instructions are as follows:

First of all, you need to remove the rubber plug located on the back of the headlight. To do this, you must first open the hood.
Then you need to remove the positive and negative terminals from the contacts.

Next, you need to press the spring bracket with your own hands and remove it from the seat.
After this, you need to remove the old light bulb and put a new one in its place.
Then you need to replace the bracket, put the terminals on the contacts and install the plug.

Note! When replacing light bulbs, do not touch their glass bulbs with your fingers, otherwise they may quickly burn out. When replacing light bulbs, you need to pay attention to the quality of the contacts.

If the contacts are oxidized or burnt, they must be cleaned

When replacing light bulbs, you need to pay attention to the quality of the contacts. If the contacts are oxidized or burnt, they must be cleaned

Replacing the fuse

If, after replacing the lamps, the low beam headlights in the Lada Kalina still do not work, you should check the fuses. They are located in the mounting block under the steering wheel.

The lamps are protected by different fuses:

Right lamp – F12
Left lamp – F13

It must be said that it is not always possible to visually identify a blown fuse. Therefore, even if it has no external defects, you should check the voltage at the terminals with a test lamp or multimeter.

Note! If, after replacing the fuse, the lighting turned on, but after a while it disappeared again, it is necessary to measure the voltage that the generator produces. It is advisable that when the engine is running it does not exceed 14.4 volts

If the voltage is higher, you can try replacing the control relay.

How to change the low beam light bulb on a Priora

Choosing which light bulbs are best for low beam on a VAZ-2114: a brief overview and new products

Priora is an extremely interesting car. The car, with its appearance, shows interest in all living things, and the same happens inside. Not as clearly expressed as in her gaze, but you will also have to feel all the delights of the design. We won’t go far, we’ll just change the light bulb. What's easier?

Replacing a low beam lamp on a Lada Priora

Light bulb is different. Several changes were made to the electrical circuit of the Priora compared to its predecessor. But we’ll talk about them later, but for now we’ll just change the regular lamp. How to change the low beam light bulb on a Priora is very clearly described in the operating instructions. It’s simple: open the lid, take out one lamp, and put a new one in. All things. But it's in the manual. In practice, things are somewhat different.

The reference conditions for replacing a low beam lamp are a table, a removed headlight unit and ideal lighting. Then it will turn out as in the instructions. In fact, the situation is somewhat different. But first, let's take a look at the manufacturer's recommendations.

To replace the left low beam lamp, it is necessary to remove the battery, otherwise there will be no access to the base. Some recommend moving the battery towards the windshield, but if you are not a philharmonic pianist, then it is better not to be lazy and remove the battery. Nerves are more expensive.
The left low beam lamp is closer to the fender, so you need to remove the rubber cover on the far left.
Power is supplied to the lamp through a block with contacts that need to be disconnected and the harness taken to the side.
The lamp itself is attached to the reflector using a spring clamp, which must be pressed from top to bottom, after which it will disengage with the hooks of the reflector.
Now you can remove the halogen and carefully insert the new H7 lamp into the headlight housing.
Having fastened the lamp to the reflector, you can put the block on the contacts and close the cover.

Replacing the right low beam lamp is similar, but you do not need to remove the battery

One more important note. All halogen lamps have a bulb that is very sensitive to dust and grease, so it is highly undesirable to touch the bulb with your hands

If you do touch it with your fingers, be sure to wipe the flask with a soft, clean rag soaked in alcohol.

Selecting a low beam lamp

If everything is more or less clear with replacing the lamp, you just need to have composure and flexibility of a boa constrictor, then with the low beam lamp itself on the Priora things are not as rosy as we would like. Firstly, a huge number of fakes littered the market, and with the same impudence as Priora looks at humanity, they replaced human lamps. It's simple - they are much cheaper.

In appearance, such a lamp is almost impossible to distinguish from a real one, and sellers in car dealerships show professional solidarity, striking in their incompetence. It is in their interests to sell us a cheap fake, and not to provide us with a good spare part, so all questions regarding the choice of lamps fell on the fragile shoulders of the car enthusiast.

There is a series of tests that is conducted from time to time by a reputable organization. During the tests, it turned out that those lamps that sell for 50 rubles apiece can have any inscription - Philips, Osram, Bosch, whatever. But these are not real H7 lamps, and their use is not only useless, but even harmful.

Low beam lamp models

Each halogen lamp has its own characteristics and necessary parameters in order to be used as a source of low beam, and this must be indicated on the packaging. In particular, according to GOST, the luminous flux of the lamp is standardized and should be within the range of 1350 - 1650 lumens. If this parameter is not indicated on the packaging, or is indicated but does not comply with the standards, then such a lamp should not be installed. The lamp power should not exceed 58 W, otherwise the wiring will be overloaded and may melt, which will lead to obvious consequences. Also, the light spot must comply with the standards in area and shape.

The best lamps for these parameters turned out to be

Philips Vision Plus +30% - if the headlight is correctly adjusted, then this lamp is quite suitable for use, provided that it is not a fake. The most ordinary good halogen.

OSRAM H7 - the most common counterfeits of this model are found. This lamp meets all standards and parameters.

H7 MEGAPOWER+30% - there is no European certification on the packaging, there is only a Russian certificate. The light spot does not comply with GOST, the base is of poor quality, and the luminous flux is 1050 lm, which is slightly below the norm. Not recommended for long-term use.

In short, this is all that can be said about the low beam headlight lamps in Priora and their replacement. Do not bring the lamp to a critical state, so as not to change it later in the cold. Choose good lamps, and good luck on your journey!

Fines

The traffic rules clearly regulate how to use head and additional car lighting depending on weather conditions, time of day and terrain

It is important for drivers to remember that the law prohibits traffic police officers from unauthorizedly opening the hood of a car or removing a headlight, checking what type of lamp is installed in the unit

The inspector stops the car if he visually observes the following violations:

Headlight adjustment does not comply with GOST. This is visible to every road user: distant lights blind passers-by and illuminate not the road strip, but the horizon.
The lights don't work or are very dirty.
The headlights do not have lenses or use lamps that are not standard for a particular model.

In addition to a fine of up to 3,000 rubles, for some violations the driver faces losing his license for a period of 6 months to a year.

For xenon

If xenon headlights are installed on a car instead of standard halogen lights and the inspector, without a technical inspection, determines that such brightness is not typical for halogen low or high beam lighting, the following will follow:

Drawing up a protocol.
Sending the vehicle to the inspection station.
Checking the compliance of lighting devices with standard ones.
Fine up to 3000 rubles. plus deprivation of rights for a period of 6–12 months if it is discovered that halogen lights have been replaced with xenon.

Xenon in foglights is also subject to fines and deprivation of rights. When choosing xenon for PTF, it is recommended to choose a lamp with a color temperature of up to 3000 K. The yellow headlight block will reduce the range of the light beam, visibility will improve without changing the brightness.

LED lamps

There is no penalty for diode bulbs in headlights if this type of light is specified by the manufacturer. If the basic version of the car in the model range has halogen installed, and a more equipped version has standard diodes, the driver can replace the halogen lamp with a diode one. Automakers provide this option for car models of the same generation.

Installing diode elements instead of the standard halogen allows you to significantly increase the brightness of the headlight, while the lighting parameters will be within the limits of the rules. It is impossible to determine which lamp is in the headlight unit without disassembling the latter. Diodes, depending on the number of blocks, provide soft, even light, do not overheat the diffuser and have a long service life.

Despite all the advantages of LED blocks, LED bulbs installed without permission also face a fine of 500 rubles. They may also be deprived of their rights for up to 12 months.

To install LEDs in headlights legally, you need to complete the following steps:

Purchase optics that correspond to the car model range.
Re-equip the lighting system in the car.
Visit the traffic police department (at the place where the car is registered), fill out an application for changes to the design of the vehicle.
Pass a technical inspection and make amendments to the diagnostic card.
Write out a certificate.

If the lamp burns out

If a car is driven with the headlights off, regardless of the reason (a light bulb has burned out, inattention, the wrong light is on, etc.), the driver faces a fine of 500 rubles. In some cases, a fine can be avoided:

If the motorist convinces the inspector that the headlight became inoperative a few minutes ago.
A fine for a non-working headlight will not be collected if the car is traveling in the direction of the service and there is confirmation - a call to the service station.
Motorists can only receive a verbal warning for not having their headlights on if it is a first inattention offense.
If all the headlights are on during the day, this is not a violation; such a point is not provided for by the rules. Therefore, the inspector may simply advise not to discharge the battery.

The most common reasons for a fine for lack of lighting:

For driving a vehicle with one headlight.
When entering the tunnel, they forgot to turn on the low or high beams; they thought that PTF or DRLs were enough.
There is no switching of lights at night when vehicles are passing.
Broken lenses do not allow you to correct the beam of light, which blinds oncoming drivers.
Using DRLs at night without headlights.

For repeated violation of the rules for the use of lighting devices on a vehicle, in 80% of cases, in addition to a fine, the driver will be deprived of his license.

There is no fine for “blinking headlights”. In rare cases, the inspector finds fault with the driver and tries to charge him with “illegal use of a light device,” but the driver can always answer that he did this, warning oncoming motorists about a possible overtaking maneuver on his part.

My headlights don't work

Sometimes none of the headlights can work in any mode. Before troubleshooting wires and components, make sure the circuit breaker is working and properly connected.

Also, even if both of your headlights are not working, you should check the bulbs and make sure they are in good condition and not burnt out.

Checking for electrical faults

Several electrical faults can prevent operation:

Blown fuse
No power in the circuit
Bad land
Faulty switch
Bad multifunction switch
Bad dimmer
Open circuit

If only the low or high beams do not work:

Check the relay for this mode.
Check the switch for this mode.

You may have to consult your vehicle's repair manual to find the relay that needs testing.

How to Check that Power is Getting to the Headlights: Use a Test Light

Disconnect the light bulb's electrical connector.
Turn on the headlights.
Connect the test lamp to a good ground and touch the test lamp probe to the power side of the connector terminal.

If the warning light is on, current flows into the headlight. Check the outlet and connector for damage, corrosion, or loose wires.

If the test light does not illuminate, check the circuit for an electrical break. Continue to the next section Finding an open circuit below.

How to check circuit grounding:

Connect the test lamp to the battery.
Touch the test lamp probe to the connector ground on the connector terminal.
If the test lamp does not light, check for an open circuit on the ground side. See the following procedure.

Some car models are equipped with special headlight modules. Consult your vehicle's repair manual for any tests you may want to do if you have a problem with one of these components.

Check the wiring diagram for your model to identify wires and trace electrical shorts and opens.

Penalty for not turning on low beams in 2020: what is the fine for running lights?

The need to adopt such amendments to the traffic rules was due to the fact that a vehicle with its lights on is more visible to others, therefore the number of accidents due to simple inattention is reduced to a minimum. It should be noted that the expected trend was confirmed in practice and the number of accidents during the daytime decreased. However, many drivers do not comply with generally accepted requirements.

The reason for this state of affairs may be simple inattention, a technical malfunction or another reason.

However, regardless of this, in case of an offense the driver may be punished. The penalty is determined by Article 12.20 of the Code of Administrative Offences.

When can a driver be issued a fine? To avoid a fine for incorrect use of lighting devices, the driver must drive with the headlights on for twenty-four hours a day.

If this condition is not met, then the driver will have to find out what the fine is for not turning on the low beam.

What is the fine for faulty headlights?

It is immediately worth noting that according to the traffic rules, the movement of vehicles with non-working lighting devices is prohibited . This applies to all lighting elements - from the size light bulb to the license plate illumination, so it is better to make sure from time to time that everything is in order.

Punishment for non-working headlights is provided for in Article 12.5 of the Code of Administrative Offences . Violation involves a fine of 500 rubles, regardless of which light bulb does not work. Naturally, if both headlights stop shining, you cannot continue driving under any circumstances; for this, you may even be deprived of your license, as this creates the risk of an accident.

Reference

Problems with light in a car occur most often at sub-zero temperatures, that is, in the winter season, because then the network is more subject to load. Also, lamps that are made from low-quality materials, from little-known or low-quality manufacturers have the greatest chance of failure.

This also applies to electrical circuit components.

Chevrolet Niva is a joint production product of two automobile concerns - AvtoVAZ and GM. The car belongs to the crossover class, but the presence of permanent all-wheel drive makes it a good option for those who like to conquer off-road conditions

Therefore, it is very important that all components of the car work reliably, because when you find yourself far from a populated area, you need to feel confident that you will be able to get to your destination

But over time, the service life of the parts is exhausted and problems appear with some elements. For example, components responsible for lighting may fail. In this case, it is impossible to continue moving.

The problem may be caused by faulty low beam lamps or wiring problems. First of all, you need to check the low beam lamps. Usually such a malfunction is easy to determine, since usually only one lamp out of two burns out.

But what to do if the low beam is not on completely and the high beam is on. The operation of the high beam indicates that the headlight unit is working properly, a problem with the contacts has been ruled out, and it is necessary to check the rest of the wiring.

To do this, you need to ring the power wire from the relay to the fuses, the relay contacts. Even if new parts are installed, this does not mean that they are in good working order. Relays and fuses can be damaged when the engine is started if the alternator is not configured correctly.

A properly working high beam indicates that the control circuit is in order. This also means that relays K4 and K5 are connected in series and control the high beam. T.

e. the problem may most likely be in the K5 low beam coil. After this, you need to check the power board.

If the circuit does not contain visible damage, it is necessary to check the contacts of relay-K5. It may make a clicking sound indicating it is working, but no signal will come out of it.

If all of the above steps did not help identify the malfunction, then you need to ring the circuit. To do this, use a multimeter or a test lamp with connected wires. It is better not to use inexpensive Chinese indicators, so as not to short the circuit.

Before performing the test, you must turn on the ignition and low beam, and then check in a certain order:

Check the voltage at the fuses. It is quite possible that both lamps burned out as a result of a short circuit or as a result of natural wear and tear.
After this, you need to turn off the relay and check the presence of voltage on pin 30. If it is missing, then most likely the problem is in the track from the wiring to K5
The cover is removed from the relay, after which you need to install it back and turn on the low beam. In this case, K5 should make a click and the plate will press against the contacts. If the light does not light up, you need to manually press the plate to ensure contact. If this action helps, then the problem lies in the relay contacts. If not, the problem is in the track on the board leading to the fuses.

The track can be ringed separately. To do this, K5 is removed, the fuses are turned off, then the multimeter contacts are connected to the fuse socket and relay 87.

If you are the owner of a Chevrolet Niva SUV, then sooner or later electrical problems may arise, just like with any other car. When any device fails, you need to correctly determine the cause of the failure.

First of all, if the current is exceeded or there is a short circuit, the fuses and relays of the Niva Chevrolet fail. Therefore, you need to know which of them are responsible for what and carry a set of spare ones with you. This article describes the main causes of electrical faults and will help in diagnosing and troubleshooting problems.

The relay and fuse box is located under the dashboard, to the left of the steering wheel. To get to the fuses, you need to open the cover. To do this, you need to unscrew 2 screws with a screwdriver.

Wiring is damaged

What if the low beam light doesn't come on because of a wiring problem? Then you need to check the blocks through which the relay and fuse box are connected. The reason may be a poor connection, or the contacts may oxidize, which leads to increased current, overheating of the wiring and failure of the lamp. To repair this damage, you need to tighten all the pad fastenings, but before doing this, do not forget to clean all contacts with an abrasive material.

In addition to the pads, you need to check the headlight switch, since the contacts on it may also be oxidized, or there may be a poor connection in this place. Any experienced technician will start searching for the cause of non-working headlights from the button to turn them on, and only after making sure that it works properly will he continue to search for the answer to the question: “Why don’t the low beam lights light up?”

The low beam light does not light up: the main causes and troubleshooting

Issues discussed in the material:

Why doesn't the low beam light come on?
Why does the low beam bulb often burn out?
Why is the low beam light dim?

If the high beam on a car is on, but the low beam cannot be turned on, then any driver would like to know what could be the cause of the breakdown. Moreover, not only used cars are susceptible to this malfunction; even on cars with low mileage, headlights can fail. In this article we will tell you why the low beam light does not light up and how to solve this problem.
